(GRANTED UNDER THE PROVISIONS F THE ACT 0F MARCH'B, 1921, 41 STAT. L., 14313.) Y

To all w /Lom t may concern VBe it known that I, HERMANN CLARE, a citizen of the Swiss Confederation, and residing at Berne, Switzerland, have invented. a certain new and useful Improvement in Envelopes (for which I have filed applications in Switzerland Dec. 15, 1916; in Germany April 27, 1917 in France Dec. 14, 1917, Patent No. 1187 ,991, delivered May 21, 1918, and in Great Britain Dec. 15, 1917, Patent No. 112,027, complete accepted Dec. 16, 1918), of which the following is a speciiication.

The present invention relates lto certain new and useful improvements in that class of envelopes in which a cut-out or transparent window is presented, for showing the address written at the head of the enclosed letter and making it serve as address for the envelope also. For the same purpose and also for the purpose of doing away with a separateletter sheet, that is making the envelope serve simultaneously also as letter sheet,

it has been proposed to `use sheets which when written upon can be folded up to forni their own envelope, in such manner that then the address written at the head of the sheet shows either on a folded-over ap; thereof or through an aperture bounded by several such flaps integrallyy extending from the sheet. For business correspondence envelopes are used on which the'senders name, address and other information is printed atV relatively high cost, which in the second named instance is reduced somewhat, it is .true, but which has the disadvantage that,

in case such a letter head from some cause becomes unusable, the printed part and the folding flaps also are wasted.

The object of the present invention is to combine the advantages of these known arrangements without at the saine time taking over theirl objectionable features, and for the purposes of my invention I provide the envelope portions forming the address space or window with gum and paste them onto the underlying letter or other contents of the envelope, and I also provide tearing lines along which these pasted-on'iiaps may be severed from the rest yof the envelope upon the latter being opened, the iiaps then remaining aflixed to the letter sheet and henceforth forming a permanent part thereof. One of these window forming portions may be printed upon in suitable manner, for instance with the card7 of the sender.

A greatadvantage over other makes of envelopes is that the party of the envelope, valuable for future reference, containing the postage stamp with theydate stamp, registry another modification of which Fig. 6 shows a section on line VF-VI.

Referring first toV Figs. 1 and 2, the envelope is preferably of rectangular shapey and its front member 1 is somewhat shorter;

,60 indications, and other data, remains perma-V than the rear member 2, so that the latter eX- tends downwardly beyond the former. Both'y members are respectively provided at their lower ylongitudinal edge with a strip ,3 and #1, and a weakened yor perforated. line -6 is interposed between strip 4 and memberi2. The latter is provided at theirlower sides extending beyond the front member V1 with laterally extending flaps 7 andB, which owing `to an interposed weakening line 9 andl10 respectively can readily be detached from the envelope body. The strips 3 and 4 and the flaps 7 and 8 are gummed, the strip '3.

on the inside and the other parts on the I outside, which latter partsin the closed envelope are bent back upon themselves. The front member 1 is provided with marginal weakening lines or series of perforations 11, so that these marginal portions can readily be torn off.

In use, the letter sheet or other enclosure is inserted into the envelope and the latter is closed by first sealing thegummed strip 3 to the enclosure, then folding over the side iaps 7 and 8 along the lines 12 and sealing them down, and finally folding overV the strip 1 on its line 6 and sealing it also to the contents. The. envelope is then securely..

closed and 'simultaneously aflixed to the con- K parts 3, Il, 7 and 8 serving as frame, is presented, into which the address can be written, unless it has not already been inserted when writing the letter. The address thus, in any case, need be written only once. The postage stamp canv preferably be a'IiiXed in thespacedesignatedv by 14, but it may, obviously, also be attached at any other point7 for instance in the upper right-hand corner. lt is thus permanently secured to the letter and serves to preserve for future reference theindication ofthe mailingplace and date. In the case of a-registered letter, for insta-nce', it cannot be claimed that no letter had been enclosed in the envelope.

`For-opening suchl a sealed envelope it is ontlopen .or11torn along the wealrenedlines 6559,11@ andll and also along the upper longitudinal bending line 'where front and back meet. The` front portion 1 may bear the senders name, address, trade-marl,and'like matter and it remains stuck to the letter sheet.

Inv'thelmodification according to Figs. 3 andd, the size of the envelope relative to the letter sheet 15, indicated by a dashdotted line, is to be such that when the sheet isinserted between the front and rear envelope members,the envelope will project on three sides- A rearwardly gummed member 16-'is sealed to the letter and to the respectively projecting marginal portions of themembers 1, and 2, which closes the en velope. lThe member 16 is provided with a cut-.out13 for displaying the address written on1 the enclosure. Along thev marginal edgesthe envelope parts may be provided with weakened-lines or series of perforations, not shown inthe drawing, along which the envelope may be opened. lf the sealing strip-lois of transparent material the'cutvoui'i'window 13, obviously, may be dispensed InA the modification illustrated in Figs. an'd'6,ithe' rear .portion 2 of the envelope is shorter than the front portion 1 by the width of a marginal strip 17, and this projecting strip which is gummed is bent upon itself and pasted to the rear face of the back portion 2, as indicated by dotted lines in Fig'. G, after the rearwardly gummed front member 1, which is provided with a cutout or transparent window 13, hasV been moistened randaiiixed to the letter or other matter inside the envelope and to the marginally projecting portions of 1` ther4 back f member 2, the gummed marginal strips 18 and 19 of the front member being sealed to corresponding strips of the back member.

The envelope is opened b tearin off these side strips and by severing the front from the back memberalong their longitudinal meeting edge, which tearing lines are indicated by the lines 20, 21, 22 and 23.

lt is to be understood that the venvelope may also be. of other shape than the obling form shown, and the space for receiving the the under side to attach it tothe contentsv of the envelope, a foldable adhesive flap on the end of the back portion and foldable adhesive flaps on the lateral edges of that part of the back portion which extends beyond the edge of the front portion, weakening lines being provided along the sides g and lbottom of the envelope to facilitate its opening.

in testimony whereofgl aiiix my signa-` ture' 1n the presence of two witnesses.
